Description

This is 25 +25W STEREO AMPLIFIER WITH MUTE & ST-BY. A stereo amplifier, often simply referred to as an “amp,” is an electronic device designed to amplify audio signals in a stereo audio system. Stereo amplifiers are a fundamental component of audio systems, providing the necessary power to drive speakers and reproduce sound with clarity and fidelity.

The TDA7265 is class AB dual Audio power amplifier assembled in the Multiwatt package, specially designed for high quality sound application as Hi-Fi music centers and stereo TV sets.

A Class AB dual audio power amplifier is an electronic amplifier that is designed to amplify audio signals with two channels (typically left and right) using Class AB amplifier topology. Class AB amplifiers are known for their efficiency and good linearity, making them suitable for high-quality audio reproduction.

Description

The STR-X6750F is power IC for quasi-resonant type switching power supply, incorporating a power MOSFET and a controller IC. The product achieves high efficiency and low noise power supply systems by the quasi-resonant operation.

An IC (Integrated Circuit) for a quasi-resonant type switching power supply is a specialized semiconductor device designed to control and regulate the operation of a quasi-resonant (QR) switching power supply. Quasi-resonant power supplies are a type of switch-mode power supply (SMPS) that offer advantages in terms of reduced electromagnetic interference (EMI), improved efficiency, and lower switching losses compared to traditional fixed-frequency SMPS designs.

Features

1. Quasi-resonant operation mode

(1) Achieves the optimal high efficiency and low noise power supply systems.

2. Current mode control

3.  Built-in PWM oscillator

(1) The PWM operates with the minimum frequency of around 22kHz, until the quasi-resonant signal becomes valid, reduces the stress on components at startup and load-shorted.

4. Built-in soft start function

5. Step-drive function, reducing switching noise
